I have a 450 lb heifer that started out with a cough and runny nose and would not eat. Got her up and worked he with LA200 on 10-01-05 no improvment. 10-04-05 reworked her with nuflor marked improvement on the cough and runny nose. Now the problem is she will not eat well at the bunks. She seems to graze and drink, but will not come up with the other most of the time. She also spends most of her day lying down away from the others. She seems a little stiff on both ends but does not appear to be sore in a foot or anything. They were moved from the sale barn second week of september. weaned and unk broke with all vacinations. Have been on 3-4 lbs of 12% creep feed since coming home. Any suggestions??
